23、g, so read on to discover the truth. Wrong idea No. 1: An invention has to be something completely new. Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright brothers, for example, got the idea for building a "flying ma

24、chine" from watching birds. Wrong idea No. 2: Inventors are born, not made. There are a lot of factors(因素) that make invention possible. Take Mazart, for example. He was born with a talent for musical composition. But other factors were also important for his creativity. His father

25、 was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"! Very successful creators dont give up when they get something wrong. As one inventor said, "A failure is the

26、 right answer to the wrong question." Wrong idea No. 3: Inventors are always old people. Dont believe that you cant invent something when you are young. Here are two examples of young inventors: Louis Braille went blind when he was a child. When he was fifteen, he invented a system

27、 of reading and writing for blind people that is still used in most countries today. As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampolin

28、e(蹦床). 54. got the idea for building a "flying machine" from watching birds. A. Mazart B. George Nissen C. Louis Braille D. The Wright brothers 55. The underlined word "talent" probably means . A. 態(tài)度 B. 品質(zhì) C. 天賦 D. 能量 56. Which of the following is the writers

30、eople D. Be an Inventor B To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade(遮蔽) against the sun. Nobody knows who first invented it, but the u

31、mbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power(

32、權(quán)力). In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens. In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believe

33、d that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power. U

34、mbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasnt until the twentieth century that the umbrellas for women began to be made in all kinds of colors. 58. Ancient people first used umbrellas as . A. a symbol of honor

35、 B. protection against the sun C. a symbol of power D. protection against the rain 59. According to the passage, the umbrella was probably first used in ancient . A. Egypt B. Babylon C. Rome D. China 60. The underlined word royal might mean " " in Chinese. A. 皇室的

37、the umbrella hasnt changed a lot since it was invented. 62. This passage is mainly about . A. the sales of the umbrella B. the differences among umbrellas C. the invention of the umbrella D. the history and the use of the umbrella C Thomas Edison was a great Americ

38、an inventor. He was born to a poor family in 1847. His mother taught him at home. He often observed things carefully and he made over 1,300 inventions during his life time. He was often said to be the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the li

39、ves of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He also said that what people called genius was mostly hard work. But Edison was a dreamer as well

40、as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them. Edison enjoyed thinking. He knew that most people will do almost an

41、ything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure. Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day h

42、e became 75 years old, someone asked him what ideas he had about life. “Work,” he answered back, “discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work. 63. Edison was . A. intereste

46、world is in danger. They hoped that governments would act quickly in order to “conserve” nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man and his technology.

47、We are changing the earth, the air and water, and everything that grows and lives. We cant live without these things. If we continue like this, we shall destroy ourselves. What will happen in the future? Perhaps it is more important to ask “What must we do now?” The people who will be livin

48、g in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometer
